Correct Answer: A

Rationale: The correct answer is Orange juice. Orange juice enhances the absorption of an iron supplement due to its high vitamin C content. Vitamin C helps in the absorption of non-heme iron, the type of iron found in plant-based foods and iron supplements. Green beans, fortified milk, and baked potato do not have the same level of vitamin C as orange juice, making them less effective in enhancing iron absorption.

Correct Answer: B

Rationale: Lispro insulin has the most rapid onset of action among the options provided. It is a rapid-acting insulin analog that is designed to control postprandial hyperglycemia effectively. Lente insulin (Choice A) and Ultralente insulin (Choice C) are intermediate-acting insulins, which have a slower onset of action compared to Lispro. Humulin N (Choice D) is a neutral protamine Hagedorn (NPH) insulin, which is an intermediate-acting insulin, not rapid-acting like Lispro. Therefore, the correct choice is Lispro.

Correct Answer: B

Rationale: Engaging in conversations about healthcare issues with a wide audience, including legislators, is a powerful way for a nurse to exert leadership and support the nursing profession. This action helps raise awareness, advocate for nursing-related matters, and contribute to positive changes in healthcare policies. Choice A, joining a local professional organization, is beneficial but may not have the same broad impact as engaging in public discourse. Choice C, registering to vote, is important for civic engagement but does not directly relate to exerting leadership in supporting the nursing profession. Choice D, learning about the healthcare system, is valuable for personal development but does not directly address exerting leadership in supporting the nursing profession.

Correct Answer: D

Rationale: The correct answer is D: IV bolus, followed by continuous infusion. In the initial treatment of hyperglycemia in a client with diabetic ketoacidosis, insulin is administered via IV bolus to quickly reduce blood glucose levels, followed by a continuous infusion to maintain control. Subcutaneous and intramuscular routes are not used in this situation as they are not rapid or predictable enough to address the acute hyperglycemia seen in diabetic ketoacidosis. IV bolus alone without the continuous infusion may not provide sustained control of blood glucose levels, making choice C incorrect.

Correct Answer: A

Rationale: The correct answer is A: Safe staffing. Safe staffing is a critical issue in nursing today due to its impact on patient outcomes and nurse well-being. While low workloads (choice B) may seem beneficial, they can also indicate understaffing, leading to burnout and compromising patient care. Increasing professional autonomy (choice C) is generally viewed positively as it empowers nurses, and improving salaries (choice D) is important but may not directly address patient safety concerns related to staffing levels.
